Refcomp SP6H5000 SP6H500E Semi-Hermetic Reciprocating Compressor for Refrigeration
Product Overview
Engineered for demanding commercial and industrial refrigeration systems, this semi-hermetic reciprocating compressor delivers reliable performance with advanced features.
Key Features
Multi-Stage Capacity Modulation: Solenoid-driven 3-step energy regulation system (100%, 66%, and 33%) dynamically matches compressor output to system loads, stabilizing suction pressure and optimizing energy efficiency.
Advanced Motor Cooling & Multi-Refrigerant Compatibility: Optimized internal gas channel directs suction gas across motor windings for effective heat dissipation. Compatible with R22, R407C, R134a, R404A, and R507 refrigerants.
Heavy-Duty 6-Cylinder Mechanical Assembly: Robust 6-cylinder design with dynamically balanced crankshaft, wear-resistant journal bearings, and precision piston-connecting rod assemblies for stable, low-noise operation.
Integrated Filtration & Safety Protection: Outer-accessible high-density suction filter screen with internal safety valve and INT6902 electronic motor protection module for comprehensive system protection.
Applications
Commercial Water Chillers: Large-scale central HVAC systems and fluid chilling plants requiring responsive multi-step capacity control.
Medium & High-Temperature Cold Storage: Fresh food storage, agricultural processing rooms, and distribution logistics facilities.
Industrial Process Cooling: Industrial cooling loops demanding continuous, low-vibration operation and reliable oil lubrication.
Supermarket Parallel Compressor Racks: Multi-compressor rack systems subjected to frequent daily cooling demand changes.

Frequently Asked Questions
Q1: How does the 3-step capacity regulation on the SP6H5000 benefit system operation?
A1: The 100%, 66%, and 33% step adjustment enables system controllers to adapt compressor displacement directly to changing cooling demands, preventing abrupt suction pressure swings and reducing electrical strain from frequent compressor cycling.
Q2: What piping connections are required for the SP6H5000 compressor?
A2: The compressor is equipped with a 54 mm (2-1/8") suction port and a 42 mm (1-5/8") exhaust port. The 360° rotatable stop valves allow flexible piping orientation, though external piping should be properly supported to eliminate strain on the connection flanges.
Q3: What routine inspection steps help maintain mechanical reliability?
A3: Maintenance personnel should regularly inspect crankcase oil levels through the sight glass, verify operating suction superheat, and check or clean the outer-accessible suction filter screen during scheduled system overhauls.
Q4: What is the MOQ and production delivery time?
A4: We maintain zero MOQ for in-stock sample orders, which can be prepared for shipment within 3 business days. Standard factory batch production orders are typically fulfilled within 10 to 15 working days.
Q5: How are Coolstart compressors packaged for overseas transit?
A5: Compressors are packed inside reinforced export wooden cases. Orders transported via sea freight are shipped with a factory holding gas charge, while air freight shipments are depressurized to comply with international aviation safety regulations.
